Be it known that I, EDMUND A. PARKER, a citizen of the United States, residing at Meriden, ycounty of New Haven, State of Connecticut, have invented a new and useful Automatic Sash-Fastener, of which the following is a specification.

My invention has for its object to provide a simple and inexpensive fastener that may be quickly and conveniently applied to either old or new windows, will require but very little cutting' of woodwork, and that without injury to or weakening of the parts, which shall comprise but a single operative part, will operate wholly by gravity and without the use of springs or other controlling parts, and will act to automatically lock both sashes the instant they are closed, lout may be readily adapted to permit slight raising of the lower sash or lowering of the Lipper sash, or both, without in any way affecting its certainty as a positive lock.

With these and other objects in View I have devised the novel automatic sash-fastener of which the following description,in connection with lthe accompanying drawings, is aspeciiication, reference characters being used toindicate the several parts.

Figure 1 is a View showing a window-jamb and the grooves for the upper and lower sashes, the parting-bead and my novel fastener appearing in front elevation, the locking and unlocking positions of the fastener being indicated by dotted lines and the meeting-rails of both sashes and the glass appearing in section. Fig. 2 is a view showing a section of the jamb on the line 2 2 in Fig. 1 looking toward the right, the parting-bead and my novel fastener appearing in side elevation and a lower angle of the upper sash appearing in elevation; Fig. 3, an enlarged detail sectional View of the fastener and the stud on which it operates, the section being on the line 3 3 in Fig. 4C; Fig. 4:, a similar sectional view on the line 1 L in Fig. 3; Fig. 5, adetail elevation of the fastener and stud, illustrating a modification in details of construction; and Fig. 6 is a detail sectional view on the line 6 6 in Fig. 5.

10 denotes a window-jamlo; 11, the groove for the lower sash; 12, themeeting-rail of the lower sash; 27, a side rail of the upper sash; 28, a side rail of the lower sash; 13, the meeting-rail of the upper sash; 14, the groove for the upper sash; 15, the parting-bead; 16, my novel fastener, and 17 a plate on which it is pivoted. The parting-bead, as is well understood, is recessed into the jamb and lies between the meeting-rails of the sashes, one or both of the sashes being provided with recesses (not shown) to receive it.

The fastener and the plate to which it is pivoted are recessed into the parting-bead, as clearly shown in Fig. 2, the fastener' correspending, substantially, in size with the portion of the parting-bead that extends outward from the jamb, so that the fastener will oscillate over the face of the jamb and in the inoperative position will lie in alinement with the parting-bead, in which position it may be locked wholly out of the Way 'of the sashes, which may be raised and lowered without the slightest interference with the fastener. The plate is secured to the jamb by screws 18, which pass through the plate from the outer face and engage the jamb.

The fastener is simply a lever and is pivoted on a stud 19, which extends from the plate below its mid-length-for example, a third, more or less, of the length of the fastener from the bottom thereof-and also in front vof the mid-width of the fastener, as is clearly shown in Figs. 1 and 4:. This is in order to make the operation of the fastener Wholly automatic. As it is required in use that the upper end of the fastener drop backward, so as to throw the lower end forward, as will be more fully explained, it is desirable to place the stud upon which the fastener is pivoted belowthe mid-length of the fastener and in front of the mid-width thereof.

In order to lend additional quickness of movement to the fastener when the sashes are closed, Iprovide the upper end of the fastener in its rear face with a dovetail recess 20, in which a weight 21, of lead or a heavy alloy, is placed.

29 denotes a-recess in the inner face of the side rail of the upper sash, into which the upper end of the fastener swings in the locking position, as clearly indicated by dotted lines in Fig. 1. By extending this recess beyond the fastener at the top it is permitted to lower the upper sash slightly without affecting the positive locking of said sash against further downward movement. By pivoting the fastener high enough in the parting-bead so that the lower end of the fastener when in the locking position will be a slight distance above the meeting-rail of the lower sash when in the closed position it is made possible to raise the lower sash slightly for ventilation without, however, affecting the positive locking of said sash against further upward movement. The extremes of oscillation of the fastener may be limited by providing a short peripheral groove 22 in the surface of the stud upon which the fastener oscillates, said groove being engaged by a setscrew 23, as in Figs. 3 and 4. In addition to limiting the oscillation of the fastener this setscrew retains it in place on the stud. If preferred, however, the inner face of the fastener may be provided with a curved groove 24, and the plate may be provided with a pin 25, engaging said groove, as in Figs. 5 and 6. In the rst form the stud may be made integral with the plate or may be tapped into it. In the second form a screw-stud is used, which engages the plate and is provided with a head 26, which engages a recess in the face of the fastener and retains the latter in place on the plate.

The operation will be obvious from the description in connection with Fig. l of the drawings. When the sashes are closed, as in Fig. 1, the fastener, owing to the manner in which it is pivoted, will tilt by gravity and the upper end will pass into recess 29 in the side rail of the upper sash and the lower end of the fastener will lie in the path of movement of the lower sash, so that should an attempt be made to raise the lower sash it will be positively barred by the engagement of the meeting-rail thereof with the lower end of the fastener, and should an attempt be made to lower the upper sash it will be positively barred by the engagement of the upper end of the fastener with the walls of the recess in the side rail thereof. By pivoting the fastener high enough in the parting-bead so that there will be a slight distance between the lower end of the fastener and the top of the meeting-rail of the lower sash when the latter is in the closed position it is permitted to raise the lower sash slightly for the admission of air without in any way affecting the positive locking of the lower sash, and by extending the upper end of the recess slightly above the upper end of the fastener, as shown in the drawings, it is permitted to lower the upper sash slightly for the admission of air without in any way affecting the positive locking of the upper sash. It will be seen, therefore, that my novel fastener may be readily adapted to permit slight movement of either sash independently of the other while leaving both sashes securely locked. To raise the lower sash above the locking position or to lower the upper sash below the locking position, the operator simply oscillates the fastener by pushing the lower end inward out of the path of movement of the lower sash, as indicated by dotted lines in Fig. l, in which position it will be retained by gravity. When the lower sash is raised, the meeting-rail will engage the fastener above its pivotal point and tilt it back into the vertical position, where it will be retained by the side rail. the side rail above recess 29 will engage the fastener below its pivotal point and tilt it back to the vertical position, where it will be retained by the side rail. As soon as both sashes are moved to the locking position, however, the upper end of the fastener will, owing to the manner in which it is pivoted, automatically swing into the recess in the side rail of the upper sash and will positively lool; both sashes, as already explained, against anything but the slight movement that may have been provided for for the purpose of ventilation.

Should it be preferred that there be no movement of either sash, but that both sashes be locked against any appreciable movement, then the fastener is placed low enough in the parting-bead so that the lower end thereof will just swing over the top of the meetingrail of the lower sash when said sash is in the fully-closed position, and the upper end of the recess in the side rail of the upper sash is made just high enough so that the upper end of the fastener will swinginto and out of said recess freely when said sash is in the fullyclosed position.

Should it be required for any purpose to dispense with the use of the fastener and leave both sashes free to be raised and lowered without locking, the fastener may be locked out of operative position by means of a bolt 30, socketed in the parting-bead and adapted to engage the end of the fastener, as indicated by dotted lines in Fig. l. The bolt is provided with a finger-piece 3l, lying in a slot in the parting-bead, for convenience in operation.

Having thus described my invention, I claiml. A sash-fastener consisting of a lever adapted to be recessed into a parting-bead and to swing over the face of a jamb and a plate to which said lever is pivoted at a point below the mid-length of said lever and in front of the mid-Width or longitudinal center thereof so that the upper end of said lever will normally swing backward into the path of movement of the upper sash and the lower end will swing Vhen the upper sash is lowered,v

forward into the path of movement of the for the purpose set forth, the upper end of IO lower sash when said sashes are in the closed position.

2. A sash-fastener consisting of e lever adapted to be recessed into a parting-bead and .to swing over the face of a jamb, and a plate to which said lever is pivoted at a point below the mid-length of said lever and n front of the mid-width or longitudinal center thereof said lever being; provided with a groove'and a weight secured in said groove.

In testimony whereof I affix my signature in presence of two witnesses.
